Kosmos 335 (Russian: Космос 335 meaning Cosmos 335), also known as DS-U1-R No.1, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 295-kilogram (650 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to study spectral ranges in the Earth's atmosphere.[1]


A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 335 into orbit. The launch took place from Site 86/4 at Kapustin Yar.[2] The launch occurred at 22:24:48 UTC on 24 April 1970, and resulted in the successfully insertion of the satellite into low Earth orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1970-035A.[4] The North American Aerospace Defense Command assigned it the catalogue number 04380.


Kosmos 335 was one of the DS-U1-R satellite.[1][5] It was operated in an orbit with a perigee of 247 kilometres (153 mi), an apogee of 391 kilometres (243 mi), 48.4 degrees of inclination, and an orbital period of 90.9 minutes.[6] It completed operations on 20 June 1970.[7] On 22 June 1970, it decayed from orbit and reentered the atmosphere.[6]
